9 March 2006 - Rain at last?

Interesting situation this evening with multiple merging boundaries across western OK and moisture backing westward in response to a speed max rotating newd over W TX. The negative impacts of ongoing tstms on low-level moisture appear to be confined to east central OK, thus this should not be a limiting factor in central OK. I expect tstms to increase in coverage by 05-06z to the west of OKC, and then spread ewd/newd overnight. Very steep lapse rates from 850-500 mb and cold midlevel temperatures could support large hail with several storms overnight. More importantly, there's a reasonable shot at 0.5-1.0" rain in Norman by 12z!
